INTRODUCTION

3Com wireless technology brings the benefits of a local area network (LAN) to
your office without the restraints and expense of network wiring. If your office
already has an Ethernet LAN, the 3Com 11 Mbps Wireless LAN can extend the
network without adding more wires.
How Does a Wireless
LAN Work?
In a traditional LAN, computers communicate through wires. Instead of wires, a
wireless LAN uses radio signals to communicate.
Netw ork Association Computers that are equipped for wireless LAN communication are called wireless
LAN clients. The wireless communication is called network association. Clients
associate through one or more access points, which are wireless base stations that
act as wireless hubs.
An access point can be connected to a wired network device such as an Ethernet
hub, switch, or router to give clients access to the wired network where they can
share files and printers and gain access to the Internet.
Roaming If the office space is large, you can set up multiple access points on the same
network to increase coverage. When a wireless client begins to lose the signal as it
moves away from an access point, it can reassociate seamlessly with another
access point. This is called roaming.
Security You can set up security to encrypt your wireless transmissions so that your data
cannot be deciphered if it is intercepted, and to prevent access to the network by
unauthorized clients.
Ad Hoc Netw orks Wireless clients can associate among themselves at close range without an access
point by using ad hoc (temporary) networks. You may wish to set up an ad hoc
network, for example, if a group is working away from the office, or if a group in
the office needs to share files apart from the LAN.

CHAPTER 1: INTRODUCTION
Setting Up a 3Com
Wireless LAN
The type of network you decide to set up depends on the size of your office and
whether or not you require connection to a wired LAN. You can also set up
security for each of the different types of networks. Your set up will probably
resemble one or more of the following examples.
All Wireless Netw orks The simplest 3Com wireless LAN consists of several clients associating in an ad hoc
network without an access point.
A simple configuration consists of one access point and several clients. The clients
can associate with the wireless network anywhere within the coverage area of the
access point. The access point is not connected to any other network segments.

PO
For more complex requirements, you can configure several access points as
separate networks at the same site. The access points use different network
identifiers called wireless LAN service areas (WLAN service areas, also called
Extended Service Set Identities or ESSID). Clients can roam within the coverage
areas of access points that have the same WLAN service areas. They cannot roam
to the coverage areas of access points that are configured with different WLAN
service areas.
Wired/Wireless An access point can be connected to a wired LAN with an Ethernet cable to create
Netw orks a mixed wired/wireless network. In this configuration, the access point provides
the link between the wired network and wireless clients. Clients can move freely
throughout the service area of the access point and remain associated with the
larger network for services such as printing and Internet access.
Multiple access points can be connected to an existing LAN to provide complete
wireless network coverage. Wireless clients can roam seamlessly between different
access points with the same WLAN service areas and remain associated with the
larger network.

from recently used WLAN service areas or from all available WLAN Service Areas
within the range of the client.
Security Settings You can set the level of security used to protect the network communications
between the client and the access point from interception by unintended
recipients. The security settings must match those that the network administrator
has set up on the network. Some security levels require you to supply encryption
settings. The levels of security are:
No Security (Open System)
40-bit Shared Key (Wi-Fi)
No encryption is used. The network communications could
be intercepted by unintended recipients.
This option encrypts the wireless transmissions to protect
your data and is compatible with other Wi-Fi certified
wireless PC clients and access points from other
manufacturers.
128-bit Dynamic Security Link
This option can only be used with a 3Com 11 Mbps
Wireless LAN Access Point. It is the highest level of security,
in which you must enter a user name and password. These
must match the user name and password set up by the
administrator on the access points with which you
associate. Each network session automatically creates a
unique, one-time, 128-bit encryption key. You never have
to enter a key.
To maintain wireless association between clients and access points, follow these
guidelines:
The security setting on the client and the access points must match exactly.
For 40-bit Shared Key (Wi-Fi) security, the encryption settings on the client and
the access point must match exactly.
For 128-bit Dynamic Security Link security, the user name and password on the
client and the access points must match exactly.
40-bit Shared Key (Wi-Fi) Encryption Settings
40-bit Shared Key (Wi-Fi) security requires you to set up encryption keys. Your
network administrator sets up encryption keys for the wireless network and gives
you an encryption string or hexadecimal keys.
An encryption string is a string of characters between 8 and 64 characters
long. The string can be any combination of letters and numbers and is case
sensitive. The encryption string can be used only with other 3Com 11 Mbps
wireless PC Cards and access points.

Setting up an Ad Hoc
Netw ork
An ad hoc network is useful when you are out of the range of an access point or
when you want to share files with others, but not with the entire network. When
two or more clients are in ad hoc mode and within range of each other, they can
communicate with each other directly through their 3Com Wireless LAN PC Cards
without an access point. One client starts the ad hoc session and names it. Other
clients can then join the ad hoc network session.
Starting an Ad Hoc Follow this procedure to start an ad hoc network session:
Netw ork Session
1 In the Windows system tray, click the 3Com icon to display the
3Com WLAN Launcher.
If the 3Com WLAN Launcher is not already running, you can start it from the
Windows Start menu. Select Start/Programs/3Com 11 Mbps Wireless LAN/3Com
WLAN Launcher.
2 In WLAN Launcher, click the Computer icon.
3 In the Ad hoc Network Login window, type a new network name in the space
provided.
This name identifies your ad hoc network to the rest of the clients.
4 Select a security setting.
You can select No Security (Open System) or 40-bit Shared Key (Wi-Fi). If you select
40-bit Shared Key (Wi-Fi), enter the required encryption information. (For details
This security setting only applies to this ad hoc network and only affects the
transmissions among the participating ad hoc clients. It does not affect security
settings for communication with access points.
5 Select the performance mode.
If only 3Com 11 Mbps Wireless LAN clients will be participating in the ad hoc
network session, click the Enhanced radio button. If clients from other
manufacturers will be participating, click the Wi-Fi interoperable radio button.

Joining an Ad Hoc The TCP/IP or NetBEUI protocol settings of clients participating in an ad hoc
Netw ork Session network session must match. For example, TCP/IP must be configured on the
same subnet and NetBEUI must be configured with the same workgroup.
After a client has started an ad hoc network session, other clients may join it as
follows:
1 In the Windows system tray, click the 3Com icon to display the
3Com WLAN Launcher.
If the 3Com WLAN Launcher is not already running, you can start it from the
Windows Start menu. Select Start/Programs/3Com 11 Mbps Wireless LAN/3Com
WLAN Launcher.
2 In WLAN Launcher, click the Computer icon.
3 In the Ad-hoc Network Login window, select the network name of the ad hoc
session you are joining from the drop-down list.
4 Set your security to match that of the client that started the ad hoc session.
5 Set the performance mode to match that of the client that started the ad hoc
session.
6 Click OK.

CHAPTER 4: SETTING THE WIRELESS CLIENT CONFIGURATION
Manually set the pow er management
When this radio button is selected, you can select the power mode manually. You
may want to select this mode, for example, if your computer cannot detect its
power source or if you want to improve performance by forcing continuous access
even though you are using battery power.
Windows NT users must select the power mode because the operating system
cannot detect its power source.
Netw ork Traffic Accelerator
If only 3Com 11 Mbps Wireless LAN equipment is being used, it is recommended
that you turn this option on to increase the rate at which traffic is handled.
Automatically release/renew the IP address
Your Internet Protocol address (IP address) contains the information that allows
network traffic to find its way to your computer.
This option requires a Dynamic Host Control Protocol (DHCP) server. The client’s
network configuration must be set to obtain its IP address automatically. For more
information on DHCP, see the documentation for your operating system.
When this box is checked, your computer automatically requests another
IP address if you travel outside of your subnet, so the network connection remains
active. Leave the box unchecked if your network does not have a DHCP server.
To force the system to release and renew an IP address, click Release/Renew Now.
You may want to click this button, for example, if you cannot establish association
with the network or if you roam in an installation that has multiple access points
and you lose network association.
Changing Your
Passw ord
The Change Password utility lets you update the password used in the access
control list of the access point with which the client is associated. This is only
applicable if you have configured the client to use 128-bit Dynamic Security Link
security.
Because access points maintain separate User Control Lists, you must update the
password separately on each access point that you associate with.
